Abstract
A field experiment was carried out at Agricultural Research Station, Kovilpatti, Tamil Nadu Agricultural University during rabi season of 2017-2018 to study the effect of different weed management practices in rainfed sesame. The experiment was laid out in randomized block design with three replications having ten different weed management treatments in rainfed sesame variety SVPR 1 under vertisol. Application of Alachlor @ 1.5 kg a.i. ha-1 as pre emergence fbQuizalofop ethyl @ 50 g a.i. ha-1 on 25 DAS as early post emergence recorded significantly lesser weed density, dry weight, weed index and higher weed control efficiency and inturn significantly produced higher seed yield (550 kg ha-1) and stalk yield (2432 kg ha-1). It was followed by the application of Pendimethalin @ 1.0 kg a.i. ha-1 as pre emergence fbQuizalofop ethyl @ 50 g a.i. ha-1 on 25 DAS as early post emergence.
